Fe is the basis. According to GOST 19282-73, it is allowed to modify steel with calcium and rare-earth elements from the calculation of the introduction of not more than 0.02% calcium and 0.05% rare-earth elements into the metal. According to GOST 19281-89 and GOST 19282-73, it is allowed to add aluminum and titanium from the calculation of the mass fraction in the rolled aluminum - no more than 0.050%, titanium - no more than 0.030%.
